    Leukemia is cancer of the body's blood-forming tissues, including the bone marrow and the lymphatic system.

    Many types of leukemia exist. Some forms of leukemia are most common in children. Other forms of leukemia occur mostly in adults.

    Leukemia usually starts in the white blood cells. Your white blood cells are potent infection fighters — they normally grow and divide in an orderly way, as your body needs them. But in people with leukemia, the bone marrow produces a large number of abnormal white blood cells, which don't function properly.

    Treatment for leukemia can be complex — depending on the type of leukemia and other factors. But there are strategies and resources that can help to make your treatment successful.

    Symptoms

    Leukemia symptoms vary, depending on the type of leukemia. Common leukemia signs and symptoms include:

    Fever or chills

    Persistent fatigue, weakness

    Frequent infections

    Losing weight without trying

    Swollen lymph nodes, enlarged liver or spleen

    Easy bleeding or bruising

    Tiny red spots in your skin (petechiae)

    Excessive sweating, especially at night

    Bone pain or tenderness

    Your body's lymphatic system is part of your immune system, which protects you against infection and disease. It includes your spleen, thymus, bone marrow, lymph nodes and lymph channels, as well as your tonsils and adenoids.

    Lymphatic systemScientists don't understand the exact causes of leukemia. It seems to develop from a combination of genetic and environmental factors.

    How leukemia forms

    In general, leukemia occurs when some blood cells acquire mutations in their DNA — the instructions inside each cell that guide its action. The mutations cause the cell to grow and divide more rapidly and to continue living when normal cells would die. Over time, these abnormal cells can crowd out healthy blood cells, causing the signs and symptoms of leukemia.

    How leukemia is classified

    Doctors classify leukemia based on its speed of progression and the type of cells involved.

    The first type of classification is by how fast the leukemia progresses:

    Acute leukemia. In acute leukemia, the abnormal blood cells are immature blood cells (blasts). They can't carry out their normal work, and they multiply rapidly, so the disease worsens quickly. Acute leukemia requires aggressive, timely treatment.

    Chronic leukemia. This type of leukemia involves more mature blood cells. These blood cells replicate or accumulate more slowly and can function normally for a period of time. Some forms of chronic leukemia initially produce no symptoms and can go unnoticed or undiagnosed for years.

    The second type of classification is by type of white blood cell affected:

    Lymphocytic leukemia. This type of leukemia affects the lymphoid cells or lymphocytes, which form lymphoid or lymphatic tissue. Lymphatic tissue makes up your immune system.

    Myelogenous (MI-uh-loj-uh-nus) leukemia. This type of leukemia affects the myeloid cells. Myeloid cells give rise to red blood cells, white blood cells and platelet-producing cells.

    Types of leukemia

    The major types of leukemia are:

    Acute lymphocytic leukemia (ALL). This is the most common type of leukemia in young children. ALL can also occur in adults.

    Acute myelogenous leukemia (AML). AML is a common type of leukemia. It occurs in children and adults.

    Chronic lymphocytic leukemia (CLL). With CLL, the most common adult leukemia, you may feel well for years without treatment. CLL is very rare in children.

    Chronic myelogenous leukemia (CML). This type of leukemia mainly affects adults. A person with CML may have few or no symptoms for months or years before entering a phase in which the leukemia cells grow more quickly.

    Other, rarer types of leukemia exist, including hairy cell leukemia.

    A sign can be defined as something that may be recognized and observed by way of a healthcare

    Rare symptoms and also signs

    The rare signs and signs regarding leukemia are as follows.

    • Choroma

    This is any tumor like collection that contains leukemia cells and it's also present under skin and or other body parts.

    • Skin adjustments

    Leukemia cutis can happen when the tissues of leukemia cell enter skin. The patches and sores may be of any particular size and so are usually tan or perhaps pink in shade.

    Leukocytoclastic vasculitis can resemble a really allergic reaction around the skin of anyone suffering. The sores can easily usually appear around the hands and furthermore feet.

    Leukaemia is cancer of the blood, where I think the white blood cells eat the red ones. It particularly hits children, but men in their 40's are also sometimes susceptible - in fact one of Australia's greatest Rugby League footballers, Ken Irvine, died from it at 45. Bone marrow transplants from a matching person can cure it in children, but finding a suitable match can be difficult.
